$geojson = 'ukraine.geojson';
$markers = [
    ['lat' => 50.45, 'lng' => 30.52, 'type' => 'capital', 'icon' => '⭐', 'name' => 'Kyiv'],
];

$generator = new GeoMapSvgGenerator($geojson, $markers, 1000, 800, true, 'uk');
$svg = $generator->generateSvg();

file_put_contents('map.svg', $svg);

Getting GeoJSON files

You can download GeoJSON files for countries, regions, or the entire world from:

• https://geojson-maps.ash.ms
• https://datahub.io/core/geo-countries
• https://github.com/datasets/geo-countries
• https://github.com/deldersveld/topojson (convert TopoJSON to GeoJSON using tools like https://mapshaper.org/)

For Ukraine specifically, you can try:

• https://github.com/flowaxy/GeoJSON/blob/main/countries/ukraine.geojson
• https://mapshaper.org/ to convert or simplify GeoJSON files

Make sure your file contains valid GeoJSON structure with features and geometry.
